As announced by Frontier at 5.36pm this evening the Beta has unfortunately been delayed once more. As Ed Lewis said here,
Despite our best efforts, unfortunately the 2.3 beta won’t be available today. We’re working hard to get it ready as soon as possible, and I’ll let you know as soon as I have more information.
Sorry for any inconvenience… I’ll keep you posted. You’ll have new information as soon as we can get it to you (more info likely first thing tomorrow).
Thanks again for your continued patience.
